DRBLLENG-MACHINB SJEEGIFECATION forming part of Letters Patent N 0.690,965, dated 5 911118137 11902- Application filed January 1-4, 1901.Serial No. 43,226. (No model.)

To ct'l/l/ w/wm it may concern.-

Be it known that I, AMOS S. JONES, a citizen of the United States,residing at Clifton, in the county of Washington and State of Kansas,have invented a new and useful Drilling- Machine, of which the followingis a specification.

This invention relates to well-drilling machines; and it has for itsobject to provide a construction which will be compact and which may becaused to occupy a small space to facilitate shipment, while the weightsof the apparatus will be advantageously placed.

A further object of the invention is to provide a construction whereinthe drill-mast may be adjusted to the proper height for use underdifferent specific conditions and means for readilyadjusting the heightof the mast from the same source of energy as is derived the drillingpower.

Other objects of the invention are to provide an arrangement of the mainwindingdrum wherewith breaking of the drill-rope will be prevented andfrom which the rope will be paid out automatically as the drillingoperation proceeds, to provide a simple and efficient system of gearingwith which the mechanism may be gradually started and which will not bedamaged should the drill become lodged in the well during the drillingoperation, and to provide a most efficient construction of bit whichwill permit the casing to readily follow the drill.

Further objects and advantages of the invention will be evident from thefollowing description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a perspective view showing the complete mechanism with thepartsin their operative positions as when drilling. Fig. 2 is a verticallongitudinal section of the complete machine. Fig. 3 is a top plan viewof the machine, the mast having its upper portion cut away and thebull-wheel being shown in section. Fig. 4. is a detail elevation showingthe clutch mechanism for throwing into an operative relation themast'adjusting mechanism, said elevation being shown by a section online 1 1 of Fig. 3. Fig. 5 is a section on line 5 5 of Fig. 3.

This mechanism comprises a frame mounted upon supporting-wheels 5 and oand including lower sills 7 and 8, the ends of which are disposed uponcross-beams 9 and 10, with which are connected the axletrees 11 and 12forthesupporting-wheels. Spacedoutwardly from the sills and lying in aplane above and parallel therewith are the longitudinal beams 13 and 14,the forward ends of which are engaged with the uprights 15 and 16substantially midway of the ends of the latter,while the rear ends ofthe beams are mounted upon rear uprights 17 and 18. At points betweenthe front and rear uprights and mounted upon the sills are intermediateuprights 19 and 20, upon the upper ends of which is dis posed across-beam 21, which projects beyond said uprights to support thelongitudinal beams. A mast-supporting cross-beam 22 is disposed upon thesills and against the rear sides of the forward uprights, and braces 23are disposed upon this forward cross-beam 22 against the forwarduprights and extend rearwardly and upwardly, with their upper ends inthe angles between the intermediate uprights and the longitudinal beams.A cross-brace 24 is disposed upon the upper ends of the uprights 15 and16, and braces 25 and 26 extend from the upper ends of the uprights 15and 16 downwardly and rearwardly and are fixed at their lower ends uponthe beams 13 and 1a in advance of the uprights 19 and 20. Other braces27 and 28 extend from the upper ends of the intermediate uprights to thelower ends of the rear uprights.

The mast of the machine comprises a lower tubular section 29, which isstepped upon the beam 22, and an upper section 30, which is disposedtelescopically therein and is provided with a rack-face 31. A slot 32 isformed in the lower section, and at opposite sides thereof are ears 33,in which is journaled a shaft 34, carrying a pinion 35, which engagesthe rack 31 through the slot A sprocket 36 is fixed upon the shaft, andengaged therewith is a chain 37, engaged also with a sprocket 38,mounted loosely upon a shaft 39, which is mounted in bearings upon thebeams 13 and 14, directly in the rear of the forward uprights 15 and 16.A clutch 4:0 is

splined to the shaft 39, and the sprocket 38 has a clutch-face 41 forengagement by the clutch when the latter is moved laterallyundertheinfluenceofitsrock-lever42. Thus if the shaft 39 be rotated andthe clutch be operated the movable section of the mast will be raised,and when raised to the proper height it is held from dropping by meansof a bolt 43, passed through both sections of the mast. To preventrearward displacement of the mast at all times, telescopic braces, eachincluding a section 44, attached pivotally to the rear portion of a beam13 or 14, and a second section 45, pivoted to the upper portion of theslidable section of the mast, are provided. Set-screws are engaged withthe sections 44 and are adapted to impinge the sections 45 to hold themin their adjusted positions.

The shaft 39 is rotated from the drive-shaft 46, which is mounted inbearings at the rear ends of the beams 13 and 14, and which driveshaftmay be rotated from any suitable source of power, as will be readilyunderstood. The drive-shaft is provided with a sprocket-Wheel 47,mounted loosely thereon at or near one end, which projects beyond thebeam 13 and has a clutch-face 48 for, engagement by a clutch-wheel49,which is splined on the driveshaft. This clutch has the usualperipheral groove, in which is engaged a strap at the end of a lever 50,pivoted upon a laterallyextending bracket 51 on the beam 13, the forwardend of the lever lying upon a rack 52, carried by a frame 53, attachedto and projecting laterally from the forward portion of the frame of themachine. When the lever is in one position the clutch is engaged andwhen in an opposite position the clutch is disengaged, and thus may theshaft 39 be thrown into and out of operative relation to the shaft 46,and when in operative relation the lever 42 may be operated, ashereinbefore described, to raise the upper section of the telescopicmast.

At the upper end of the mast is a yoke 53, and between the arms of thisyoke and near to the upper ends thereof is pivoted a walking-beam 54,which projects forwardly and rearwardly from the mast, the rear end ofthe beam having the upper section 54 of a connecting-rod pivotedthereto, the lower section 55, with which the upper section is slidablyconnected, having connection with the crank 56.01: a crank-shaft 57,which is mounted in hearings on the beams 13 and 14. The sections of theconnecting-rod are telescopically connected, as shown, and are providedwith set-screws 58 for holding them adjustably. The crank-shaft 57 is intwo sections, as show1i,upon the inner ends of which are fixed spacedcrank-disks 59 and 60, which are connected by an eccentric-pin,which isthe crank 56. These disks act as guides to prevent lateral displacementof the connecting-rod upon the crank-pin in all positions of the pin.The

disk 60 forms one end of a flanged pulleywheel 61 upon one of theshaft-sections and through the medium of which the shaft is rotated tooperate the Walking-beam.

To rotate the pulley-wheel 61, a main drivepulley 62 is fixed upon thedrive-shaft 46, and connecting this main drive-pulley with the pulley 61is anormally loose belt 63. When the pulley 61 is to be rotated tooperate the walking-beam,this belt is tightened by means ofabelt-tightener consisting of a rocker 64, fixed upon a crank-shaft 65,which is mounted in hearings on beams 13 and 14. The rocker includesspaced plates, as shown, ex tending at opposite sides of thecrank-shaft, and between the plates and at the ends thereof are mountedpulleys 66 and 67. The pulley 66 bears against the upper face of theupper portion of the belt, and the pulley 67 bears against the lowerfaceof the lower portion of the belt, and when the shaft is rocked therocker is operated to move the engaged portions of the belt toward eachother, as will be understood, and thus take up the slack of the belt,when sufficient friction will be established between the belt and thepulleys 61 and 62 to transmit power from one pulley to the other. Torock the shaft 65, an angular rock-lever 68 is pivoted to the upright 16and is connected by means of a rod 69 with the crank of the shaft 65.The lever 68 has a knife-edge for engagement with a rack 70 on upright16 to hold the lever, and thus hold the rocker in adjusted position. Anydesired tension may be thus given to the belt, and should thewalking-beam be prevented from operation from any cause the belt willslip, and thus breaking of parts of the structure will be prevented.

Mounted in bearings upon the beams 13 and 14 and directly in the rear ofthe shaft 39 is a shaft 71, on which is fixed the winding-drum 72 forthe drill-rope 73, said drum having a gear 74 at one end with whichmeshes a gear 75 upon shaft 39 for rotating the winding-drum from shaft39. The windingdrum is thus thrown into operative relation with thedrive-shaft and at the same time with the shaft 39.

The drill-rope passes from its winding-drum upwardly and over a pulley76, mounted in the yoke 53, directly below the walking-beam, and thenoutwardly and over a second pulley 77, which is mounted between thesides of a secondyoke 78, which is pivoted upon the forward end of thewalking-beam, with the sides of the yoke straddling the beam. The stem79 of the yoke extends upwardly, and a rod 80 is pivoted thereto at oneend and to. the upper end of the yoke 53 at its other end, this rodlying parallel with a line connecting the pivots of the walking-beam andthe yoke 78, whereby as the walking-beam is rocked the yoke 78 is heldat all times in vertical position, while the drill-rope is preventedfrom playing backwardly and forwardly upon the pulleys excepting whenthe drill is undergoing adjustment.

To prevent unwinding of the drill rope ICC) from its drum during thedrilling operation, a friction-brake is provided and consists of a strap81, one end of which is attached to the beam 22, while the other end isattached to a spring-plate attached to and depending from thecross-brace 24. The strap intermediate of its ends is wrapped around theshaft 39, and the spring-plate acts to draw the strap with sufficienttension to frictionally engage it with the shaft. This frictionalengagement is sufficient to overcome the weight of the drill, but isnevertheless so slight that should the drill become stuck the upwardmovement of the walking-beam will draw off from the Windingdruin anamount of slack to compensate for the movement of the said beam. At thelower end of the spring-plate is a handle 82, which may be grasped tomove the spring-plate in a direction to slacken the brake-strap andpermit the shaft 39 to turn freely when the winding-drum is to beoperated or the mast to be raised.

The sand-drum (shown at 85) is mounted loosely and slidably upon themain drive-shaft and is adapted to frictionally engage one end thereofwith the side face of the drive-pulley 62 and when in this position willbe rotated thereby; To thus shift the sand-drum into and out offrictional engagement with pulley 62, said drum has aperipherally-grooved hub extending from the outer end thereof, and withthe groove of this 11 uh is engaged the yoke at the end of an angularlever 86, mounted on the beam 14. A second angular lever 87 is mountedon the side face of beam 11 and is connected by means of a rod 88 withlever 86 for operating the latter to shift the sanddrum.

To accommodate the sand-line 89 from the sand-drum,a crane-arm 90 oftriangular shape is providedand is pivoted to the lower section of themast. The outer end of the cranearm is bifurcated and provided with aguidepulley 91, over which the sand-line is passed. A guide-arm 92 isvertically disposed at the base of the crane-arm, and the sand-line istaken between this guide and the mast,whereby when the crane-arm isswung laterally from its operative position (shown in Fig. 1) thesand-line will be retained by the guide in engagement with the pulley.This arrangement of the sand-line permits it to be swung entirely out ofthe Way when not in use.

The face of the drive-wheel 62 opposite to the sand-drum is recessed andprovided with an internal gear 93, with which is engaged a pinion 94upon a shaft 95, mounted in bearings on beam 13 and 0,11 a supplementalbeam 96, disposed parallel with beam 13 and supported upon beam Zland apost 97 on beam 10. On said shaft between beams 13 and 96 is fixed abrake-drum 98, with which cooperates a shoe 99 at the end of a lever100, pivoted in the bifurcated upper end of a post 101 on sill 7. Thisbrake-lever extends forwardly of the machine to be grasped and operated.
